Some sources list the husband of Ann/Anna Sprague as perhaps Robert Lawrence; Eugene Aubry's "Plymouth Colony" lists her husband as William Lawrence. I also show a Robert (William) Lawrence married to Mary Sprague, Ann's sister.

Listed in the 1627 cattle division, and thus presumed to be the third person with Francis Sprague in 1623. William Lawrence married a daughter of Francis Sprague who should have been born before the 1623 sailing. It is therefore assumed that Anna was his daughter and not his wife, but there is no direct evidence on that point.S1
